1 Claim.

The invention relates to devices for opening and closing, particularly, the upper sash of a window and has for its main object to provide means whereby this sash may be lowered and raised with great ease. Another object is to so construct these means that they will be practically unnoticeable when not in use. A further object is to make the device adjustable to sashes of different widths and construction. A still further object is to provide a device of simple and strong construction, which is easily attached to the sash and which can be manufactured at low cost.

These and various other objects and advantages will be readily understood from the following description and from the accompanying drawing of a couple of preferred embodiments of the invention in which, however, modifications may be made without departing from the scope of the invention. In the drawing Fig. 1 is a front elevation of a window to which the device has been attached,

Fig. 2 a similar view showing the upper sash in a different position,

Fig. 3 an end view of the device itself,

Fig. 4 a side view of the device,

Fig. 5 a bottom view of the device,

Fig. 6 a fragmental side view of a sash showing a modification of the device,

Fig. '7 a fragmental side view of a member shown in Fig. 6, and

Fig. 8 an end view of the device shown in Figs. 1 to 5 but attached in a different manner.

Referring first to Figs. 1 to 5, a window frame is shown at 10, an upper sash at 11 and a lower sash at 12. The device is attached to the upper frame of the upper sash, as shown in Figs. 1 and 2. It consists of a rail 13 on which an operating rod 14 is slidingly mounted. The rod is suspended from a shoe 15 which slides in the rail and which is provided with a pair of lugs 16 in which a flattened portion 17 of the rod is hinged on a pin 18. The body of the shoe is circular so that it may be turned in the rail, and the rod terminates in a finger grip 19 at its lower end.

The rail is attached to the sash by screws 20 and 21. The screw 21 is of the round headed type so as to form a stop for the shoe so as to prevent its withdrawal from the rail. A plurality of holes 22 are punched in the end of the rail and in any one of these holes the round-headed screw may be inserted so as to cause the shoe to stop at the approximate center of the sash. By providing these holes the sash may be used on sashes of different widths.

When the operating rod is not in use it is pushed to the position indicated by the dotted lines 23, in which position it rests against the side frame of the sash and is hardly noticeable. It will be seen that the circular shape of the body of the shoe enables the finger grip 19 to be turned in any direction most convenient for use, and that, when the rod is in the position indicated in 23, the finger grip may be placed fiat against the frame of the sash.

In Fig. 2 the upper sash is shown partly lowered and the operating rod is shown pushed toward the left side and tilted so that it may be dropped between the sashes to assume the position shown at 23.

Fig. 8 shows the rail attached on the outside of the upper frame of the sash instead of on the under side as in the other views. The joint between the shoe and the rod makes this manner of attachment possible.

The modification shown in Figs. 6 and 7 em- 75 ploys a rod 24 instead of the rail used in the other device. A bar 25 slides on this rod. One end 26 of the rod is flattened, bent downwardly and secured to the side frame of the sash by screws 27. The other end of the rod is supported by an angle iron 28 secured to the top frame of the sash by screws 29. An elongated slot 30 is punched in the upper end of the bar 25 so that it may be tilted on the rod 24 to enable it to be dropped between the upper and lower sashes. Its inoperative position is shown at 31.

Having described my invention and its use, what I claim as new and wish to protect by Letters Patent is In combination with a window sash; a substantially fiat rail, having inwardly extending flanges on its lower side, attached to the under side of the upper frame of the sash and extending from one side thereof to some distance beyond its center; a shoe slidingly and rotatingly mounted in p said rail; and an operating rod suspended from said shoe and having an operating handle, the operating rod being hinged to the shoe so that the angle between it and the sash may be altered as the sash is lowered and raised and so that it may be lifted over and dropped behind the lower sash of the window to be placed in its inoperative position when the upper sash is opened, and the top of the shoe being fiat so as to engage with the flat part of the rail to prevent the shoe from sliding sidewardly in the rail when an upward force is extended on the operating rod.
